a uniaxial force is a force applied only in one direction - directly in the axis direction
Number of planes in the uniaxial joints?
It is defined as the ratio of the uniaxial stress over the uniaxial strain in the range of stress in which Hooke's Law holds
Uniaxial crystals have one optic axis, where the refractive index is the same in all directions perpendicular to it. Biaxial crystals have two optic axes, with different refractive indices along each direction. This causes different light paths and behaviors in biaxial crystals compared to uniaxial ones.
Columns.
There are two types uniaxial or biaxial.

Uniaxial crystals have two different refractive indices: ordinary index (no) and extraordinary index (ne). The ordinary index is the same in all directions, while the extraordinary index varies depending on the direction relative to the optic axis of the crystal. This anisotropic behavior is a characteristic feature of uniaxial crystals.
They have one plane of movement. ex: elbow
a state of strain in which two of the three principal strains are zero
humeral-ulnar joint (elbow), tibial-femoral joint (knee)
Applying uniaxial strain to materials can change their mechanical properties. It can increase strength and stiffness, but may also decrease ductility and toughness. The specific effects depend on the material and the amount of strain applied.
